New Delhi, March 19 (NationPress) As Indian-origin NASA astronaut Sunita Williams and her colleague Butch Wilmore successfully returned from space after a remarkable nine-month mission, experts celebrated their journey as a landmark achievement in science and technology.
Williams and Wilmore made history as the first to fly on Boeing's initial Starliner spacecraft, which launched in June of last year. What was intended to be an eight-day mission extended to a remarkable 286 days in orbit.
Following numerous delays, the astronaut team safely landed on Earth early this morning aboard SpaceX's Dragon spacecraft.
"Everything went smoothly, and now they are back, marking a significant celebration of science and technology, and showcasing their ability to overcome numerous challenges while in space," stated Dr. P.K. Ghosh, a space strategist, in an interview with IANS.
Ghosh described the event as "a tremendous achievement," emphasizing that behind each space mission, "hundreds and thousands of individuals contribute their efforts."
“An unforgettable moment! The safe return of Sunita Williams and Butch Wilmore represents human resilience, collaboration, and the spirit of exploration,” remarked scientist Narottam Sahoo, an advisor at the Gujarat Council on Science and Technology, via a social media post.
“This extraordinary journey underscores how science, precision, and teamwork are essential for successful space exploration. Every mission inspires us, showcasing that with determination and innovation, even the toughest journeys can culminate in a safe landing,” he added.
Meanwhile, Ghosh highlighted the inherent risks and challenges associated with spacecraft landings.
“The descent angle is crucial. If it’s less than what the spacecraft can handle, it will deviate from its intended path,” Ghosh explained.
“If it comes down too steeply, the spacecraft could be damaged. Hence, it must be executed with precision,” he continued.
Furthermore, Ghosh noted that as the spacecraft re-enters the Earth’s atmosphere, intense friction occurs due to external temperatures.
Additionally, the spacecraft's velocity must be decreased to ensure a safe splashdown, he remarked.
When questioned about why SpaceX's Dragon took 17 hours to return to Earth, he clarified that the "actual travel time between Earth and the International Space Station is a mere 55 minutes."
However, he explained, the 17-hour duration accounts for spacecraft checks and the final clearance from the Earth-based control station, according to Ghosh.
The nine-month tenure of Williams and Wilmore aboard the ISS raised concerns regarding their well-being due to the unexpected extension.
Ghosh reassured that the astronauts are well-prepared through "rigorous training." They even undergo blindfolded exercises.
In these exercises, "they must accurately identify every switch among the hundreds available. That is the standard of training they receive," he stated.
The space strategist also pointed out the health challenges astronauts may encounter during prolonged space stays.
“Space impacts nearly every part of the body. The heart and kidneys are affected, and the most significant issue is radiation, which can also affect DNA,” Ghosh added.
“Interestingly, astronauts may also experience an increase in height upon returning to Earth,” he concluded.
